Title: Control to protect catalytic converter during engine malfunction
Inventor: DENZ HELMUT
IPC: F02D41/22
Filed: 1991-01-18
Abstract: A method of controlling operation of a fuel-injected engine to protect a catalytic converter for the engine exhaust gas from overheating comprises a step (s1, s2) of testing, by a diagnostic process, whether each injection valve of the engine fuel injection system still closes correctly. If this is not the case and the engine is not operating at full load, in a further step (s5) the mixture of fuel and air for all cylinders is enriched and injection cut-off during engine overrun operation is forbidden. This ensures that the quantity of oxygen reaching the converter in all load ranges is limited in such a way that harmful after-burning does not take place in the converter. The converter is thereby protected against overheating, but operation of the engine can continue. <IMAGE>

Title: Precharging DRAM bit lines to half supply potential
Inventor: FOSS RICHARD CHARLES
IPC: G11C11/4096
Filed: 1991-04-05
Abstract: To sense the contents of a memory cell in a DRAM with improved speed, wherein both sides of a data bus pair 2, 3 are precharged to one-half the supply voltage level, the midpoint between a logic high and logic low level. Only a small voltage differential from the aforenoted intermediate level caused by connection to the bit line pair 1 is necessary to cause the sense amplifier to successfully read. A differential amplifier having a high gain region over that small differential is used to sense the differential, providing an output representative of the charge imparted to the bit line and thus to the data bus from the read-memory cell. During a cycle, one side of the data bus is pulled high by sense amplifier 7 and the other side is pulled low. Since the bit lines are precharged to half supply potential, full logic levels are achieved more quickly during a read cycle. <IMAGE>

Title: Computer display incorporating moving video images
Inventor: LIVESLEY RAYMOND MALCOLM
IPC: G09G5/00
Filed: 1995-02-28
Abstract: A computer display system for displaying a sequence of video images in at least a portion of a graphic display comprises means for receiving the sequence of video images. The images may be from either an external source or from a program running on a computer. A set of data defines a predetermined size and position of the portion of the graphic display in which the video images are to be displayed. Video images are inserted into the thus defined portion. Furthermore, the data defining the size and position of the portion for graphic display can be selectively intercepted and modified thereby changing the position and size of the portion of the display into which the video images are inserted. In one embodiment video images are primarily displayed in a first mode. Changes in video image data as monitored to determine when playback of the sequence of images commences or ceases. Playback switches to a second mode of display in response to commencement of playback and then reverts to the first mode of display in response to termination of playback of a sequence of video images.

Title: Investigating stress induced anisotropy in boreholes
Inventor: SINHA BIKASH K
IPC: G01V1/44
Filed: 1995-04-05
Abstract: Low and high frequency flexural waves are generated with dipole transducers. From measurements made at receiving transducers which are oriented at two orthogonal directions in a horizontal plane normal to the borehole axis the received signals are transformed into arrivals as a function of frequency such that the principal polarization directions and the magnitudes of the maximum and minimum wave velocities at those directions are determined at different frequencies. If the maximum velocity of the relatively low frequency flexural waves are in a first principal polarization direction, and the maximum velocity of the relatively high frequency flexural waves are in a second principal polarization direction which is substantially normal to the first principal direction, uniaxial stress in the formation is attributed to stress induced azimuthal anisotropy as opposed to an intrinsic anistropy in the formation. Then, the low frequency information can be utilized to obtain values for formation shear stress parameters. <IMAGE>
